Copy Objects

Learn how to copy and move objects

Copy objects

You can copy objects between buckets or within the same bucket. Currently only objects up to 5 GB can be copied using the API.

When making a copy of an object, the owner of the new object will be the user who initiated the copy operation.

Copying objects within the same bucket

To copy an object within the same bucket, use the copy method.

1
await supabase.storage.from('avatars').copy('public/avatar1.png', 'private/avatar2.png')

Copying objects across buckets

To copy an object across buckets, use the copy method and specify the destination bucket.

Move objects
